The invention relates to a wound dressing and a method for producing a wound dressing with a marker material for indicating a condition of a wound, in particular a microbiological wound milieus. The invention is characterized in that the wound dressing has a contact side which is formed by a biocompatible monofilament fabric of monofilament threads with a smooth surface and in that on the monofilament fabric on its upper side facing away from the wound at least one cover element is fixed which is provided with the marker material.

The present application relates to an electronic wetness-sensing absorbent article and related methods. The electronic wetness-sensing absorbent article includes a flexible waterproof thin film; at least two mutually separated and insulated flexible electrodes disposed on one surface of the flexible waterproof thin film; a water-permeable braided fabric layer; and an absorbent layer disposed on the other surface of the flexible waterproof thin film, located between the flexible waterproof thin film and the water-permeable braided fabric layer, and adapted to absorb a liquid entering from the water-permeable braided fabric layer. The flexible waterproof thin film, the flexible electrodes, and the liquid contained in the absorbent layer form a non-polar variable electrolytic capacitor. The wetness state of the electronic wetness-sensing absorbent article is obtained by detecting the capacitance value of the variable electrolytic capacitor and change thereof.

An absorbent article includes a topsheet layer, a backsheet layer and one absorbent core layer. The topsheet layer, absorbent core layer and backsheet layer each include a longitudinally directed side peripheral edge. The absorbent article further includes an aqueous medium-sensitive coating composition for triggered release of active ingredients from the absorbent article. The aqueous medium-sensitive coating composition is affixed to the absorbent article adjacent a longitudinally directed side peripheral edge. The coating composition includes a betaine ester or betaine ester derivative having a functional active group derived from a fragrance with a hydroxyl group, a color changing visual indicator chemistry, where the visual indicator chemistry is selected from at least one of the group of a pH indicator dye and pH adjuster, a thermochromic dye and a polarity-sensitive dye.

A product for monitoring the condition of the wound comprising a biologically inert matrix which absorbs wound exudate and one or more reagents on or in the matrix for measuring one or more markers comprised within the wound exudate. A change in the one or more reagents caused by the one or more markers comprised within the wound exudate provides a visual indication of an alteration in the condition of the wound. Companion wound dressings, kits and methods are also provided.
